EdgeTech-6205-Bathy-StJohns

Sonar imaging systems and underwater technology provider EdgeTech has successfully carried out on-water testing of its new 6205 bathymetry system to map St. John’s Harbor.

Demonstrated during the Canadian Hydrographic Conference, EdgeTech’s recently introduced 6205 bathymetry system was able to gather co-registered bathymetry and side scanned sonar data in less than three hours.

The collected data was then processed to create a bathymetric map of the entire harbour and the “Narrows” entrance to the harbour.

Equipped with an advanced transducer array configuration and signal processing techniques, EdgeTech 6205 can maintain IHO accuracies out to ten times water depth, and collect true side scan data.

Traditional multi-beam systems cannot operate at simultaneous dual frequencies and have narrow three to four times water depth coverage, which take more time to measure and have previously proved to be inefficient in shallow waters.

The newly designed EdgeTech 6205 can use co-registered side scan sonar imagery surveyors and data processors to cross reference and verify features or targets when cleaning the bathymetry data to be certain real features are not deleted from the data set.

EdgeTech’s 6205 system is also available in an AUV version, the EdgeTech 2205. It has been installed on many AUVs for high-resolution 3D maps of the seafloor.
